It was mentioned briefly earlier, but the outboard motor industry has not forgotten about the 2-stroke. Take a look at the BRP offerings in particular such as Evenrude's E-tec line from 25 to 250 hp if you want to see what a modern 2-stroke might look like next to it's 4-stroke rivals.
Are they better than their 4-stroke competition? Maybe, maybe not, but they are certainly comparable if not better in almost all categories. Power to weight, noise, pollution, maintenance cost, etc The only thing they seem to suffer from is public perception, as it's true their forefathers were smokey, polluting enviro-disasters. But these new-tech motors are very impressive.
Snowmobiles are one of the few other places were development has kept pace between the 2 and 4 stroke, and again they are easily comparable. Heck, most mountain sled riders I know wouldn't have a 4-stroke as weight is just so critical to those guys.
So I don't think you can argue that the 2-stroke is dead-end technology. It's simply the victim of political maneuvering.
